We operate a cluster of Sun Xeon IA32 servers with Centos 3.5. Nodes are installed via a host-specific kickstart script which is generated for each node from a master template. Thus all kickstart scripts are clones of the master, edited for hostname, IP address etc only.
The CENTOS 3.5 ISO images are exported from a server & that remote NFS mount is also configured in the master template. This works perfectly well & a fully automated installation requiring no operator intervention results.
We recently added some new Opteron nodes to give us some 64-bit capability. These of course, use a slightly different master kickstart template as they mount up a different ISO directory from the NFS server, which contains the x86_64 version of Centos 3.5.
When we install these 64-bit nodes, however, we get the message: "that directory could not be mounted from the server". On hitting OK we get the usual dialogue box which displays our chosen server IP and the correct x86_64 ISO directory, if we OK that, the NFS installation proceeds unattended as normal.
I think we saw a similar thing with redHat 9 NFS kickstart installations but it was quite variable.
Anyone seen that with CENTOS3 or RHEL3 & got any clues ?
TIA
